The fact that altering your ulimit changes the behavior indicates that 
your OS's pthread implementation is broken. We cannot fix that. We use 
the documented, portable pthread API to specify the stack size that we 
need for each thread, and it seems your platform will not honor our 
request without you raising your ulimit. The stacksize ulimit should 
only affect non-threaded processes, or the main thread in a threaded 
process. It should not affect any threads created by the application, 
especially when we set an explicit size at thread creation time.

So you have to set an explicit ulimit before starting slapd. This is no 
different from having to set the nfiles limit on some platforms to raise 
the number of available file descriptors. That's an administration 
detail, not a software bug.
